Polyvinyl alcohol (PVA) resin is a kind of heavy polymer. It is usually a white or slight yellow floccules, flake, granular orpowdery in appearance.PVA is non-toxic, insipid and non-polluting. PVA is a kind of water-soluble resin with good chemical stability. It also has good adhesion, film-forming ability, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical chemical properties of polyols and can make esterification, etherification, acetalization reactions.Application:It has a wide range of uses, such as pastes, coatings, adhesives (such as transparent glue), stabilizers, dispersants,emulsifiers, thickeners, sensitizers and fillers, and nasal glue (toys).-Improves bonding strength-Improves smoothness and surface gloss-Improves oil resistance and abrasion resistance-Improve film forming properties and chemical stability

PVA, full name of polyvinyl alcohol, is a common water-soluble polymer with good adhesion, film formation and emulsification stability. It is widely used in many fields, including:
1. textile and paper industry: as a sizing agent, adhesive use.
2. Construction industry: Used in the manufacture of tile adhesives, putty powder, etc.
3. Coatings and inks: as emulsion stabilizer and film forming aid.
4. Adhesive: Preparation of various types of glue.
5. Medicine and cosmetics: Used as a thickening agent in eye drops or as a film forming agent in cosmetics.
6. Other applications: such as raw materials for the manufacture of vinylon fiber, and some special purpose film materials.
